| Abstract: | Pheromone components of female California red scale,Aonidiella aurantii (Maskell) were isolated from airborne collections and found to be 3-methyl-6-isopropenyl-9-decen-1-yl acetate and (Z)-3-methyl-6-isopropenyl-3,9-decadien-1-yl acetate. Both enantiomers of the latter compound as well as the corresponding enantiomers of theE isomer were prepared from (S)- or (R)-carvone. Bioassays with each of the four isomers showed that only theR,Z isomer attracted male red scale.Aonidiella aurantii (Maskell) (Homoptera: Diaspididae).This research was supported by a USDA Cooperative Research Grant. |
